GCC ISE Cert Import - Resolution

Resolution

Deregistered all nodes except PSN-04 from the ISE deployment and re-registered them. All re-registered nodes synced successfully and the deployment is functional.

Remaining Work

  • PSN-04 — requires certificate reissuance before it can be re-registered to the deployment

  • Confirm all policy sets and endpoint data replicated correctly post-recovery

  • Schedule follow-up with GCC/Matt to address PSN-04 cert

Outcome

  • 3 of 4 nodes restored to full operation

  • Deployment functional for authentication and policy enforcement

  • Evan led the engagement as primary ISE engineer for NE-Systems
